Abstract

Busbar safety is a protection system that plays an important role in securing the disruption of the busbar itself. This protection system should work in a sensitive, selective, rapid, and must be stable to disturbance outside the region busbar protection. At the substation Amlapura, if one busbar impaired or absence of the busbar securing safety as on the other substation, will lead to an imbalance perceived by the system and can lead to continuity of power flow can be disrupted. Based on the calculations that have been done shows that for short circuit simulation results busbar A and B obtained Amlapura substation fault current that occurs in the amount of 5.538 kA. For the calculation of the impedance zone 1 (80%) primer is 1.9721 + 5.715 ? A Zsekunder with a time delay of 0 seconds or work instantly, Zone 2 (120%) primer is 5.55 ? Z + J 16.0836 primary, Zone 2 (120%) the secondary is 2.958 + J 8.5726 ? Zsekunder with a time delay of 0.4 seconds.

Abstract

Ground wire is one of the lighning protection instrument used in medium voltage distribution network with the intention to reduce interference due to lightning strikes. On the feeder Serangan the ground wire put 4 – 5 wicket. To know effective gap of ground wire is put on the feeder Serangan then used effectiveness ground wire parameters and total of disorder by lightning strikes directly or indirectly. From the analysis is obtained the effective gap on scenario 4 by 3 – 4 wicket. Choosing scenario 4 is as effective gap because seen by economic aspect, as longest gap point put of ground wire then the cost needed to use material and the installation of ground wire will be cheaper.  DOI: 10.24843/MITE.1501.05
